Abstract :
The authors address discrete-time control systems containing a memoryless nonlinear element and show that, when a hypothesis analogous to the circle condition for the stability of continuous-time systems is met, corresponding propositions hold concerning the relationship between the nature of the error response and the system type. A convergent algorithm is given for computing the limit of the steady-state response whenever it exists. Results are also given concerning certain special cases
